EN 14726 Analysis of Copper and Copper Alloys Testing
The European standard EN 14726 provides a comprehensive protocol for the chemical analysis of copper and its alloys, which are widely used in various industries including mining. This standard ensures accurate and reliable determination of copper content in raw materials, semi-finished products, and final products. The method is based on atomic absorption spectrophotometry (AAS) and is suitable for quantitative assessment.
The process involves careful sample preparation to ensure the integrity of results. Raw samples are typically ground into a fine powder using a laboratory mill, ensuring homogeneity across the entire specimen. This step is critical as any irregularities could lead to inaccurate readings. The prepared samples undergo digestion in a strong acid mixture, which dissolves the matrix and releases copper for measurement.
Following digestion, the solution is transferred to a clean beaker where it is analyzed using atomic absorption spectrophotometry. This technique measures the absorbance of light by atoms in the gaseous phase, providing precise quantification of elemental concentrations. The accuracy and precision of this method are validated through inter-laboratory comparisons and traceability to primary standards.
EN 14726 is particularly important for mining operations where copper content can significantly impact product quality and market value. Compliance with this standard ensures that materials meet specified purity levels, which is crucial for downstream processing and final product performance.
The scope of EN 14726 covers both pure copper and its alloys, including brasses, bronzes, cupronickels, and other compositions containing significant amounts of copper. The method is designed to analyze trace elements down to the ppb (parts per billion) level, making it suitable for detecting even minor impurities that could affect product quality.
The methodology described in EN 14726 is widely accepted within the European Union and internationally due to its rigor and reliability. Compliance with this standard is essential for companies looking to ensure consistency across their supply chain and meet international quality standards.
Scope and Methodology
